Rebelscum has a report apparently based on an internal Toys R Us presentation that mentions three new vehicles for The Vintage Collection - an all-new speeder bike that includes a possibly new Biker Scout and a tripod cannon; a re-release of the big AT-AT in a ROTJ box, possibly with Endor deco; and an ESB redeco of the 2010 Slave I with Han in carbonite. The speeder bike and AT-AT are apparently limited to 30,000 pieces (though I don't know how that stacks with any other exclusive - the only other number they've ever released is the 50,000 for Target's 2005 lava Vader) and slated for release October 1, with details on the Slave I being somewhat vague.
Hasbro confirmed the speeder bike a while back, and I've been looking forward to a new one for quite a while. Hopefully it delivers.
I thought that the 2006 Endor AT-AT was frankly a little unnecessary, given that we only see an AT-AT on Endor for a few seconds (and then see its side for a little longer, but still). Shelling out even more money for a larger version strikes me as something of a "well, all right" purchase. But provided it's somehow new, I'll still get it, of course. I wonder if they'd change the sounds to be more ROTJ-specific?
I'm surprised that they'd want to release the Slave I and big AT-AT at the same time - the last two years have only had one "big box" item per store (well, there was the Vintage AT-AT at the same time as the TCW Slave I, but that was just a repack). There's also going to be the MTT, so there will be quite a few big items this fall. Still, it'll be cool to get the OT Slave I, as we all knew it was coming sooner or later.
